Embodiment Construction

[0016] The present invention will be described in further detail below, so that those skilled in the art can implement it with reference to the description.

[0017] The invention provides a processing technology of polymer oil-absorbing paper, comprising:

[0018] Step (1) dissolving polylactic acid and poly 3-hydroxybutyrate caproate in an organic solvent to prepare an organic phase of a mixed solution of polylactic acid and poly 3-hydroxybutyrate caproate;

[0019] Step (2) dissolving ammonium bicarbonate in water to prepare the water phase, the concentration of ammonium bicarbonate in the water phase is 4.3~6.7g / L;

[0020] Step (3) adding natural fiber into the water phase, the length of the natural fiber is 30-50 μm, first carry out ultrasonic treatment to the water phase, the frequency of ultrasonic treatment is 80-90KHz, the time of ultrasonic treatment is 15-20min, and then the organic Divide the phase into 4 to 7 parts, add them to the water phase one by one, and pe...

Abstract

The invention discloses a processing technology of polymer oil absorption paper. The processing technology comprises the steps that 1, an organic phase of the mixed solution of polylactic acid and 3-hydroxybutyrate caproate is prepared; 2, ammonium bicarbonate is dissolved in water to prepare a water phase; 3, natural fiber is added to the water phase, the length of the natural fiber is 30-50 microns, ultrasonic treatment is conducted on the water phase, the ultrasonic treatment frequency is 80-90 KHz, the ultrasonic treatment time is 15-20 minutes, then the organic phase is divided into 4-7 parts and is added to the water phase part by part, homogenizing treatment is performed after each part of organic phase is added, and emulsified liquid is obtained; 4, the emulsified liquid is put at normal temperature for 1-2 hours, then the temperature is reduced from the normal temperature to 5 DEG C, and standing continues at the temperature of 5 DEG C for 1 hour; 5, standing is performed at the temperature of 10-15 DEG C for 3-4 hours. The prepared oil absorption paper has good oil absorption capacity.

Description

technical field [0001] The invention relates to a processing technology of polymer oil-absorbing paper. Background technique [0002] In beauty and skin care, oil-absorbing paper or oil-absorbing film is an important auxiliary tool for facial care, mainly used to absorb and remove oily substances secreted by human facial skin. There are many disadvantages in current oil-absorbing paper or oil-absorbing film. For example: powdery oil-absorbing papers will fall off during storage and use; natural fiber oil-absorbing papers may damage delicate skin when used; modified fiber oil-absorbing papers may have chemical raw material residues that are transferred to The site of action can cause allergies. Therefore, need a kind of oil-absorbing ability more effective, to the oil-absorbing paper of skin nonirritating effect. Contents of the invention [0003] The invention designs and develops an oil-absorbing paper with better oil-absorbing ability and no stimulating effect. [00...
